'SEL'F-IGNITING BURNER.

SPECIFICATION tbrming part of Letters Application filed July 22, 1903.

To all whom it may concern.-

Be it known that I, GUSTAV OBERLAENDER, a citizen of the Empire of Germany, residing in New York, borough of Bronx, and State of New York, have invented certain new and useful Improvements in Self-Igniting Burners, of which the following is a' specification,

It is well known that when a current of combustible gas impinges against platinum sponge the sponge is brought to incandescence and the gas ignited thereby. It has been proposed to arrange such platinum sponge in the central part of the incandescentmantle; but it has been found that with such an arrangement some time elapses before ignition takes place and thata considerable quantity of gas -gathers -.in the upper and lower parts of the mantles, which when the sponge is brought to incandescence explodes, whereby the attendant concussion accompanying the ignition of the gas causes an appreciable decrease in the'life of the incandescent mantle, and so aggravates the main objection frequent renewal-of the same. a

This invention relates to self-igniting burners in which it is only necessary to turn the cock of the burner, and so permit a current of gas to impinge against a platinum sponge tubular'part of' the burner, and in this manner ignite the gas as soon as itleaves the burner without the objectionable explosion.

The objectof this invention is to obviate the objections'abovereferred toby providing a device which is simple to manufacture and which is commendable for general adoption.

For this purpose the invention consists in a I self-igniting burner comprisinga burner tube,

with an incandescent mantle.

a foraminated wall in said 'burnehtube a'rranged transversely thereto, and means sup ported within saidburner-tub'e adapted to be brought to incandescence when impinged by a current of combustible gas for igniting the same, as will be fully described hereinafter and finally pointed out in the claims.

In the accompanying. drawings, Figure 1 represents a front elevation of my improved self-igniting burner, showing the same as used Fig. 2 is a cen- Patent No. 757,218, dated April 12, 1904.

tral section of Fig. 1, showing the location of 5 theigniter. Fig. 3 shows in detail the igniter shown in Fig. 2. Fig. 4 shows the igniter provided with spring-legs, whereby itmay be sprung into place in the upper part of the burner and retained in position by the spring action. Figs. 5 to 9 are modifications of the igniter, in which Fig. 5 shows a small incandescent mantle provided with a platinum sponge. Fig. 6 shows a lantern-shaped igni:

ter consisting of a perforated cylinder in which is supported a platinum sponge. Fig.

7 shows an igniter consisting of a platinum sponge supported by a gallows-shaped support. Fig. 8 shows an'igniter consisting of a rod supporting a platinum'sponge arranged 5 transversely to the burner, and Fig. 9 shows a different form of burner provided with an igniter. 1 Similar letters of reference indicate corresponding-parts.

Referring to the drawings, A represents a gas-burner which is provided at its lower part with the usual air-openings a and. with a chimney 6, provided with openings 6 at its lower part. The burner is also provided with a mantle-supporting rod 0,'which is vertically adjustable by means of a. screw 0, which supwire w, which supports a platinum sponge 7/, provided with a piece of platinum i For preventing the igniter I from being displaced or removed by the force of the gascurrent the legal of the igniter, as shown in 9 Fig. 4, are given a spring action, by means of which they may be compressed and inserted in the upper part e of the burner, so that when the pressure is released they are maintained in the'fupper part of the burner.

In using my improved burner it is only necessary to turn the cock of the same, and so permit the combustible gas to'impinge against On the top of the burner is 30 i sariiy be impinged by gas,

Instead of the simple igniter shown in Figs. 3 and 4, different forms may be used, as shown 5 to 9, in which Fig. 5 shows asmall incandescentmantle m, provided at its interior with a platinum spongem, which is supported by a rod m, provided with a slotted part wa whereby it is saddled on the tubular part of the burner. In Fig. 6' is shown a perforated cylinder n, provided with a diametrically-arranged framen, whichsupports a platinum sponge n and which is provided with an eyelet n at its upper end, through which passes a supporting-rod'n, which=is provided with a on the tubular upper parteof the burner. In Fig. 7 is shown an up right 12, provided with apart p bent at right angles to the same, which supports a platinum wire 2, to which is fixed a platinum sponge p,

the lower end of the platinum wire p being connected with a part p. The upright rod 12 is supported by a disk 12, which also supports the 'partp and which is provided with one or more perforations p for the passage of the gas. The

burner shown in Fig. 7 is for the adaptation of this special kind. of igniter provided with a part e, having an opening 6, in which the disk 0 is seated. In Fig. 8 the upper part 6 of the burner is provided with sockets r, in which is supported a transversely-arranged rod 1-, which supports the platinum wires 1*, to which is fixed a platinum sponge r". In Fig. 9 a further modification of the igniter is shown as applied to a different kind of burner s, which is provided with air-openings s, terminating in a mixingschamber 8 The upper part a of the burner s is provided outlet openings g and a circular cavity 8, the bottom 8 of which is foraminated,

the botemanating from the perforations s of tom 8 serve to bring the igniter to incandescence, whereby a flame is formed on the upwith gaswhile the per part of the burner, which is fed from gas emanating from the openings g.

Instead of the different forms of igniters shown many others may be substituted, the main feature ofthe invention being in the arrangement of the igniterin the upper part of the burner proper, whereby the current of gas of the burner comes in contact with the platinum sponge, which immediately yet gradually ignites the gas.

The great disadvantage of gas burners which 'hascaused many to adopt the electric lightnamely, the use of matches-is overcome by my improved self-ignitingburner, as it is only necessary by the use thereof to turn the cook of the burner. Matches are 'not only very often a source of inconvenience, but are also objectionable on account of the danger-of fire attendant the use of the same. Furthermore, when the gas-jet of the improved igniter is accidentally left open th whereby the flame produced will giveknowledge of the fact. The ignition of the gas will have the further advantage thatthe gas will beignited and burned while emanating from the burner, and so remove the danger of gas asphyxiation. When applied to gas-burners provided with incandescent mantles, the absence of explosions'withattendant concussions insures a longer life to the same, no matches are required for its ignition, and all (injury caused by falling matches is obviate burner by any one without requiring any changes in the same and may be, due to its simplicity, manufactured at a low cost, giving thus ample reason for general adoption.

I claim as new anddesire'to secure by Let ters Patent- A self-supporting burner, comprising a burner tube, a foraminated wall in said burner-tube arranged transversely thereto, and meanssupported within said burner-tube below the upper edge of the same and above the foraminated wall, adapted to be brought to incandescence when impinged by a current of combustible gas, substantially as set forth.

In testimony that I claim the foregoing as my invention I have signed my ence f two subscribing witnesses.
